Can you swap from using unleaded 91 to a higher octane petrol. I'm told you get better fuel consumption from higher octane petrol I have a Holden Vectra

There is no problem making the change from a lower octane to a higher one.

It’s probably worth the effort to confirm either way, whether you detect a change in fuel consumption and performance or not.

If you don’t believe there is any benefit you can always change back.
